Encapsulation of an optically nonlinear octupolar guanidinium cation in a host polyanionic L-monohydrogentartrate lattice leads to noncentrosymmetric orthorhombic P2 1 2 guest-host crystalline structure with cell parameters a=11.347 (2), b=11.162 c=6.668 (2) A Z=4. Final R=0.049 from 1229 independent reflections. The packing shows strong interlocking between the anionic and cationic sublattices by multidirectional hydrogen-bonding network. optimally oriented for 222 crystal point group is...
New noncentrosymmetric crystals including the 2-amino-5-nitropyridinium and 2-amino-5-nitropyridine chromophores have been designed following a strategy first applied to dihydrogen phosphate. If counteranion able self-aggregate in chains or layers as (H2PO4-)n is associated cation, structure based on herringbone motifs systematically formed. In same way it has observed that bulky group grafted amine radical of induces containing molecular entities. The structures dichloroacetate ionic...
2-Amino-5-nitropyridinium halides have been synthesized and their crystal structures determined. The of acentric phases reveal networks non-linear chromophores arranged in herringbone motifs. Their secondharmonic generation responses vary magnitude between that 3-methyl-4-nitropyridine N-oxide 2-methyl-2,4-dinitrophenyl aminopropanoate molecular compounds. Chained anions screen favourably the interactions cations phases, while reverse situation is observed centric phase...
